CHILTERN Railways is offering free train tickets to anyone running the London Marathon on Sunday, April 28.

The rail service provider will have the offer for one day only, just for those people tackling the 26-mile challenge.

Passengers will be required to show their race numbers to Chiltern staff at the gates and on the train.

The rail firm is also putting on extra services, to help runners’ supporters heading to London, with one between Banbury and Marylebone at 6.40am and another from Aylesbury to Marylebone via High Wycombe at 7am.
